APPARATUS FOR WINDING COPS OR BOBBINS OF YARN.

SPECIFICATION forming part of Letters Patent No. 613,384, dated November 1, 1898. Application filedDecember 8,1897. Serial ITO-661,208. (No model.)

To aZZ whom, it may concern:

Be it known that 1, WILLIAM J. MCCAUS- LAND, a citizen of the United States, residing at Camden, in the county of Camden and State of New Jersey, have invented certain new and useful Improvements in Apparatus for Vinding Oops or Bobbins of'Yarn; and

I do hereby declare the following to be a sufficiently full, clear, and exact description thereof as to enable others skilled in the art to make and use the said invention.

This invention relates to machines for winding cops or bobbins upon tubes, and particularly to that class of bobbins or cops wound upon conical tubes, and has for its object the winding of the yarn firmly upon the tube and the avoidance-of slipping upon the surface of the tube and of the entangling of the yarn by the outer layers sinking into or forcing-the inner layers of the yarn out of proper position.

To accomplish this end, this invention consists of a series of ridges raised above the surface of a supporting-body so opposed in diagonal or oblique direction to the circles or rings of yarn as they are wound upon the coptube or bobbin as to press the yarn as it winds firmly toward the base of the'cop or bobbin and firmly hold and smooth the layers of yarn into proper position, so that the succeeding layers or rings of yarn will not sink into and entangle with those previously wound, it being understood that the ridges move relatively to the cop 'or bobbin around upon the circle of yarn, as'well as press upon it. In some forms of the invention the ridges form the means of propelling the cop or bobbin in winding and in others are stationary, the yarn and bobbin alone turning, as will hereinafter appear.

The construction and operation of the invention are hereinafter fully described, and shown in the accompanying drawings, in which Figure 1 shows an elevation of the driving mechanism made in one form in which a conical roller is used for the propelling mechanism. Fig. 2 shows in elevation another form in which a cylindric roller is employed. Fig. 3 shows in plan another form in which a flat surface is employed. Fig. 4 shows a partiallysectional view in which a hollow conical propelling-surface is employed; and Figs. 5, 6, 7,

and 8 show the helical ridges as applied to winding cops upon cylindric or slightly-tapering bobbins in a conical cup, respectively in elevation in lengthwise section and of a cup shown separately in section and in end view.

Referring to the drawings, 1 represents the arbor of the driving-surface. In Fig. 1 this is a cone marked 2,'the surface of which is threaded or formed with ridges 3 in helical direction, (or in the manner of threads of the quick or multithreaded screw,) which ridges 3, contacting with the surface of the yarn 6 on the cop-tube 4, propel it in rotation, and as they propel it press the yarn 6 toward the greater end of the cop-tube. The direction of the rotation is indicated by arrows drawn in full lines and the direction of the resultant thrust is indicated by arrows in dotted lines. The cop-tube 4 is supported or directed by a spindle 5 in the usual manner, so that as the yarn increases the diameter of the cop it raises the cop, and the yarn 6 is guided to the cop-tube in the usual manner by a traversing eye 7, which reciprocates so as to place the yarn in the desired circles or layers.

As shown in Fig. 2, instead of a conical surface a cylinder 8 is used to propel it, having threads or segments of threads 9 formed upon it, which act in like manner as explained in relation to the form shown in Fig. 1.

In Fig. 3 the propelling-surface is a disk which has spiral ridges formed in evolute curves, which may be either continuous or interrupted, as shown at 10 and 11 in the drawings, the pitch or inclination being such as to throw outwardly toward the greater end of the cop-tube 12. In Fig. 4 the propelling-sur face is a dished or hollow one and has similar threaded ridges directed in helical and evolute curves, so as to press the yarn toward the greater end of the cop-tube.

In the form shown in Figs. 5, 6, 7, and 8 the bobbin 13 is placed on and rotated bya spindle 14, driven by a whirl 15. The bobbin 13 is cylindrical in form or but very slightly tapering, and the yarn 6 is guided by a reciprocating eye 7 through a slit 16 in a conical cup 17. In the interior of the cup 17 are helical ridges 3, which press the yarn 6 as-it winds in the bobbin 13 toward the greater end of the cup 17 and insures the laying of the several layers of yarn firmly upon each other. The spindle 14: is susceptible of endwise motion, and as the yarn winds upon the bobbin 13 in conical layers it presses the cop and bobbin outward from the cup 17. In this form of the invention the spiral or helical ridges, although not propelling the yarn or cop as it forms on vthe bobbin, act as guides to smooth and press the several layers of yarn upon each other, as the ridges in the forms shown in Figs. 1, 2, 3, and 4.

The leading feature throughout the invention is that the ridges of the propelling and guiding surfaces press the yarn toward the greater end of the cop-tube and secure tight and firm winding thereon, so that there is no slipping possible during the winding process, and as a consequence the successive layers are all firmly wound without sinking into or entangling with those beneath them, thus avoiding much of the waste incident to ordidary conical cop-windin g operations. Heretofore efforts to prevent such slipping of the thread have been made by forming ridges on the cop-tube itself or by roughing the surface, so as to prevent sliding, and also by winding within conical cups or sleeves; but none of these are effectual, the successive layers loosening those beneath, and as the loosened yarn moves toward the smaller end of the cone the several layers become entangled. By the above-described device I am enabled to wind firmly sound cops without entanglement of the different layers with each other, even upon polished tubes, and the unwinding of such cops for use is not attended with any waste. The forcing orpressure upon the yarn as it is wound is continuous by this operation toward the greater end of the coptube up to the last layer of the yarn, and there is no tendency whatever to loosen from the commencement of the winding to the end of the process.

Having described this invention and the apparatus and mode of practicing it, what I claim is 1. In an apparatus for winding cops or bobbins a body provided with helical ridges, a cop or bobbin support, adapted to support a cop or bobbin with the yarn thereof in contact with said ridges and means for rotating one of said parts to thereby press the yarn toward the base of the cop or bobbin.

2. In an apparatus for winding cops or bobbins, a body having a series of ridges thereon and means for rotating it, a rotatable support for a cop or bobbin adapted to support the cop or bobbin with the yarn thereof in contact with said ridges, means for guiding the yarn to said cop or bobbin, said ridges being diagonal to the circles of yarn in said cop or bobbin and adapted to impart rotation to the latter and to press the yarn toward the base thereof.
